Example Questions
Example Question #41 : Life Science
What similarities are there between this father and his offspring?
Similar size, same exact colors, and fur.
Similar colors, face, shape, fur, and nose.
These dogs have no similarities.
Similar colors, face, shape, fur, and nose.
These dogs are similar in many ways. They both have similar types of fur and colors (the puppy has some brown so his mother may have brown in her fur), their nose and face are similar shapes, and they look like the same breed of dog. Parents and their offspring are usually very similar.
Example Question #10 : Observe How Animal Offspring Are Similar To Parents
If a mother and father both have blonde hair and brown eyes, what would their child most likely look like?
Red hair and green eyes
Blond hair and brown eyes
Brown hair and blue eyes
Blond hair and brown eyes
The child would look similar to his or her parents because offspring usually have similar characteristics to their parents. The offspring would probably have brown eyes and blonde hair as well.
Example Question #1 : Patterns In Behavior Of Parents And Offspring
Baby birds will chirp and cry to let their parents know they are hungry and want food. The parents know to bring them food when they hear the cries. One parent stays and watches the babies while the other goes to collect food.
How are the parents and offspring behaving to help them survive?
They are behaving poorly and will not survive.
They are working together.
They all work on their own.
They are working together.
The parents and offspring are working together to survive. The babies have learned to call out for food and the parents know this means the babies are hungry. The parents have a system to watch the babies and collect food so everyone is safe.
Example Question #2 : Patterns In Behavior Of Parents And Offspring
Bird 1: Does not prepare a nest ahead of time, lays eggs near the ground in a weak nest.
Bird 2: Builds a strong nest ahead of time, lays her eggs in the nest high up in the trees.
Which bird is behaving in a way that will help the babies survive?
Both birds
Bird 1
Bird 2
Bird 2
Bird 2 is behaving in a way to help her babies survive. She has picked a spot high in the trees away from predators and humans, she has built a strong nest, and she is ready for her eggs.
Example Question #3 : Patterns In Behavior Of Parents And Offspring
How do some animal parents help their young grow up?
Animals do not help their young grow up.
Protect them, feed them, and teach them skills.
Leave them alone to learn everything.
Protect them, feed them, and teach them skills.
Some animals help their young grow up by protecting, feeding and teaching them skills. Many animal parents pass on patterns of behavior to their offspring so they can survive and grow into adults.
Example Question #4 : Patterns In Behavior Of Parents And Offspring
Animal groups and their babies stay close together to help them survive.
False
True
True
This statement is true. Many animal groups are careful to keep their babies close to them or in the center of the group, so they don't get lost or hurt. Elephants, for example, move all the babies to the middle when traveling, so they aren't able to get away from the group.
Example Question #1 : Determine How Parents And Offspring Behave To Survive
What behavior is this mother using to keep her baby safe?
The baby is carrying the mother.
Playing with her baby and having fun.
Carry her baby and keeping it close.
Carry her baby and keeping it close.
The mother chimpanzee in this photo is carrying her baby and keeping it close. The baby is not as fast as the mom or able to climb as well, so carrying the baby means it can keep up and won't get lost. The mothers keep the babies safe this way.
Example Question #1 : Patterns In Behavior Of Parents And Offspring
What is this mother cat doing to help her kittens survive?
Feeding them
Hugging them
Taking a nap
Feeding them
This mother cat is allowing her kittens to nurse and drink milk. She is in charge of feeding them to keep them alive. If she did not behave this way, the kittens would have no milk.
Example Question #1 : Patterns In Behavior Of Parents And Offspring
Why would this bear show its babies how to climb a tree?
To get away from the babies
To keep them safe
To have fun with them
To keep them safe
This behavior that the bear is showing is a way to stay safe and find food. Bears are great climbers, but they have to learn! Mother bears will show the babies how to climb, what foods are in threes to eat, and show that when they are in danger, they can climb the tree to safety.
Example Question #8 : Patterns In Behavior Of Parents And Offspring
Monkeys using tools is a survival behavior.
True
False
True
This is a true statement. Monkeys make tools to scare away snakes or predators, to play with, and to find food. Monkeys can push a stick into an anthill and then eat the ants off of it. They also will wave the sticks at a snake or hit them with it to scare them away from the group.
